The OMEGA® HHP350 Series smart
manometers brings high precision
and value to handheld manometer
users. Standard accuracy is ±0.05%
FS, including temperature effects,
with ±0.025% FS optional.
Models are available for gage,
absolute or differential pressure with
available ranges from 10" of water
to 3000 psi.
Additional features for the HHP350
series include MIN/MAX capture,
adjustable damping rates, and user
selectable auto shut-off time period.
It can also document up to 240
readings automatically or manually.
Saved readings can be recalled at
any time.
